## CODR - LOGIC

The link to the problem CODR - LOGIC  riddle problem is:

https://www.spoj.com/problems/CODR/

The problem is riddle which stimulate your thinking skills.

Notes:
1) The first important thing is the input ends when n=0.
2)Consider the example of the test case given the problem.
Input:
`124`

Output:

`0208100`
Consider the output is divide as follows

02 08 100
a0 a1  a2

and input as

1   2    4
b0 b1 b2

The output is obtained by:

a0 = b0 * b1;
a1 = b1 * b2;

. . . . . .
Be careful while printing the output if it a0 or a1 is a single digit then append "0" while printing like
(e.g.: 02).

Now here comes the twist most of coders leaving the question without solving the question as it is a wrong question with wrong test cases but it is not  :) .

Now we need to use the a0 and a1 we need to subdivide the digits to get the logic.From above test case we have taken as per logic going.

a0                             a1
0   2                        0    8
p0  p1                     p2   p3

From above division of a0,a1,a2 we now going to a2.
a2
1  0     0
q1     q2

q1 = p1 + p3

q2 = reverse(p0+p2)

So a2 = append(q1,q2)

So we now got the a0 a1 a2 so we can print the output for the testcase. Similarly, for other test cases.

The CPP solution for  CODR - LOGIC:

#include <iostream>
#include <cstring>
#include <algorithm>
#include <string>
using namespace std;
int reverses(int n1)
{
int r,c=0,sum=0;
while(n1>0)
{
r=n1%10;
n1=n1/10;
sum = sum*10+r;
}
return sum;
}
int main()
{
int n;
cin>>n;
while(n!=0)
{
int a0,a1,a2;
a2 = n%10;
n= n/10;
a1 = n%10;
n= n/10;
a0 = n;
string an0,an1;
int b;
a0=a0*a1;
if(a0/10==0)
{
cout<<"0"<<a0;
}
else
cout<<a0;
a1= a1*a2;
if(a1/10==0)
cout<<"0"<<a1;
else
cout<<a1;
int l1,l2,l3,l4,l5,l6;
l1=a0/10;
l2=a0%10;
l3=a1/10;
l4=a1%10;
l5=l1+l3;
l6=l2+l4;
string se1,se2;
se1=to_string(l5);
se2=to_string(l6);
reverse(se1.begin(),se1.end());
cout<<se2<<se1<<endl;
cin>>n;
}
return 0;
}

Happy Coding......
